London Olympics organizers say 3,800 tickets were reclaimed and put on sale to the British public for Tuesday events.

Criticism of blocks of empty seats has led organizers to try to recover tickets given to national Olympic committees and sport federations that will not be used. Organizers then put the excess tickets for sale online to the British public.

Organizing committee spokeswoman Jackie Brock-Doyle says the sale for Tuesday events covered 30 sessions and 15 sports. She says almost all tickets were snapped up shortly after they went on sale.

Brock-Doyle says ticket availability will change daily. She expects the allotment to shrink as events move closer to finals.
